FWIW, I’m ok with all of the rule changes last year. It’s different, but none of it changed the essence of the game.
Even the 7 inning doubleheaders, made a day of baseball more digestible. DH, no big deal, already part of the game. Three batter rule, extra innings rule, I hardly noticed frankly.
Legislating against the shift is more important. The shift encourages swinging for homers and turns LHH into a disadvantage. Restricting shifting would be far more beneficial than changing any of the COVID rules.
